each end of the transverse opening of the doo-r 5 so that said bearing rings are disposed at opposite sides of the inner end portion or the tube 5. Transverse sockets are providedy in the sides of they inner end portions dt the lock bolt-9, and normally register with transverse openings provided through the tube and the bearing rings 13, locking pins being arranged within the openings or the bearing rings 13 and retracted out or the pockets 14 of the bolt 9 by means or springs 16 that are preferably or' the helical compression type and which have their outer ends bearing upon heads 17 provided upon the outer ends of said pins 15, the inner ends vor the springs 16 being in '-1 contact with shoulders provided by counter-boring the outer portions of the transverse openings in the bearing rings 13 as shown.

The lock embodies a knob spindle composed lot' an inner section 18 having a cylindrical reduced inner end journalled in the-inner bearing ring 13 and having an axial socket of angular cross section opening through the inner end thereof. The knob spindle further includes an outer section 19 that has a reduced cylindrical central portion journalled within the outer bearing ring 13 vfrom which projects a rurther reduced inner end portion 20 of angular cross section that snugly lits within the socket of the spindle section 18 and which may be secured in said socket in the well known manner by means of a set screw indicated in cross section at 21 in Figures 2 and 3.

The squared inner portion 20 of the outer knob spindle section 19 passes through the open opposite side of the bolt 9 and has a shoulder block 22 securedfthereon, the shoulders of which cooperate with shoulders'on the interior of the bolt 9 as indicated at 23 in Figure 1 for causing retraction of the bolt 9 upon rotation or the knob spindle. The knob spindle and block 22 carried thereby are normally held and yieldingly returned to a position wherein the bolt 9 is allowed to be projected by means or a spring 24 that is attached to the block 22 at its innerend and is arranged upon a pin 25 carried by a transverse partition 26 or the like provided interior-ly or `the bolt 9 near the outer end of the latter, the outer end vor the spring 25 bearing against the -member 26 as shown clearly in Figure 1.

Sleeves 27 and 28 are respectively disposed with their inner ends against the outer sidesot the bearing rings 13 and the outer end'ot the spindle sections 19 and 18 are respectively secured within the inner ends or said sleeves 27 and 28 respectively by means vor a transverse rivet 29 and the set screw 21,

the innerends of the sleeves 27 and 28 being journalled in central openings provided in escutcheon plates 30 secured against opposite sides or the door with their openings coincident with the transverse opening in the door. Suitable knobs, preferably formed or pressed metal, are secured upon the outer end .portions or the sleeves 27 and 28, the larger outer end portions or the knob central sections 18 and 19 lit snugly in against the outer ends or ythe knob spindle l by means of a screw 34 or the like, and each or said plates 32 is provided with a plurality or resilient wings 35 each of which is secured to the outer end or one of the rods 32, whereby said rods are normally withdrawn or retracted from the bearing rings 13 so as toallow the locking pins 15 to automatically return to retracted bolt releasing position, and the rods 32 are or such length as to have their inner ends normally lie outwardly of the bearing rings 13 whereby said rods 32 will not interfere with the free turning movement of the knob spindle, and whereby the bolt 9 may normally be readily retracted.

A cylinder 36 is rotatably disposed within the outer end of the sleeve 27 while a further cylinder 37 is arranged within the outer end or thesleeve 28, and said cylinders are both provided upon their inner ends with marginal inwardly projecting cam members 38 that are of annular form, and disposed with their inner cam edges in contiguous relation with the outer ends of the rods 32. -The cams 38 are so` formed that when they are disposed in one position, both or the rods 32 associated therewith are allowed to retract for permitting the locking pins 15 to release from the bolt,l

and when in another position, to force said rods 32 inwardly and so retain the same for moving the locking pins 15 into the socket 14 of the bolt 9 and retaining the locking pins 15 thus disposed. This desired form is provided by making the cams or a two point type when vonly two locking pins and operating rods are provided at each side.

The cylinder 36 is retained within the sleeve 27 by means of the outer end wall of the adjacent knob 31 which abuts an outturned flange 39 provided on the outer end or said sleeve 27, and said cylinder 36 is provided with a central key receiving slot ory opening 40 that is coincident with a key hole 41 provided centrally in the outer end i engage the adjacent sleeve for preventing rotation of said cylinder relative to the last mentioned sleeve.

f latter are rotated to one position, the locking pins are held in locking position and when moved in another position, said pins are allowed to move to released position, said lock bolt having a casing extending at right angles to the knob spindle, bearing `rings arranged at opposite sides of said bolt casing, and in which the knob spindle is journalled, said locking pins being `carried by said bearing'r'ings.

4.
